Powers/Abilities: Mordoo had training in the mystic
arts, and his powers included speaking to spirits and reversing the aging
process. His spells were cursed; anyone who requested the performance of
a spell would have that spell backfire on them.

History: (Journey into Mystery I#75/3) - Mordoo was
a gypsy with a reputation for being able to perform any magical feat requested
of him. He also had the stigma of bringing hardship to those who made these
requests. Franz Kopnik visited Mordoo and asked him to make his lover Katrina
Steuben a young woman again. Mordoo was reluctant, but after Kopnik taunted
him he agreed. Mordoo successfully turned the middle aged Steuben into a
teenager, but she suddenly changed her mind about marrying Kopnik. She started
coming on to Mordoo, and he eagerly accepted her advances.

As with many 1950's and 1960's Marvel monster stories, this
story is not confirmed as part of Earth-616 continuity, but there's nothing
to exclude it either. --Leave it in unless something rules it out!--Snood.

Kopnik was a 50 year old bachelor spending time at a vacation
resort in the Bavarian Alps. He met a woman named Katrina Steuben and soon
considered marrying her. His only reservation was a desire for a much younger
mate. He asked the sorcerer Mordoo to give Steuben back her youth. Steuben
was turned into a teenager, but she no longer wanted anything to do with
Kopnik. Kopnik could do nothing as she fell into Mordoo's arms.
